[Technical field to which the invention belongs] The present invention relates to the installation of movable valves and diaphragm valves related to flushers, which is suitable for low power or high water pressure effects. At the same time, it can improve the flushing force and achieve better flushing. Cleanliness, in more detail, especially refers to a double-f valve flusher, which can be used where the flusher can achieve low power and power saving as an instant flushing effect to increase the flushing effect. [Prior art] According to the conventional flushing device, for example, the patent No. 822 1 5238 "flushing valve" patent is roughly composed of a body, a movable valve, a fixed frame, a power supply, a supply and It consists of an electromagnet. Among them, the body is provided with a cavity inside, a water inlet can be connected to a side thereof, a water inlet can be connected to the lower end, a water outlet can be connected to the water outlet, and a partition is sealed at the top. A column is passed through the center of the partition, and a shell is arranged at the top of the body. The movable valve is installed in the cavity of the body and can be used to control the communication between the inlet and outlet channels. The fixed frame is fixed to the body. The power supply is fixed inside the housing and is connected to the electric eye fixed on the housing. The electric power supply can be cut off or turned on by the electric eye. The electromagnet is sleeved. It is placed on a fixed frame and is powered by a power supply. Its iron core can usually block the pressure relief channel at the top of the cylinder, so that the pressure-tight chamber formed by the partition above the movable valve and the partition cannot conduct the drainage bubble through the bubble pressure channel. Press' and when electromagnetic When it is excited, its iron core moves upwards, so that the water stored in the pressure relief chamber can be discharged through the hole in the movable valve through the drain of the carcass. At this time, the movable gate will be caused by the water pressure difference And move up to make the water channel and drain

1240786 V. Description of the invention (2) The water channel is opened to carry out the flushing action of the urinal. [Summary of the Invention] The flush valve of the conventional patent case is a single valve design of a movable valve. The single valve flusher still has the following many unsatisfactory points that need to be improved: 1 · Because the flush valve is adopted The single-valve one-stage design, so its core needs to directly block the pressure relief channel on the diaphragm, which causes the electromagnet to operate with large power, resulting in more power consumption. Therefore, it is necessary to increase the number of coils of the electromagnet, which will result in The volume of the electromagnet becomes larger. In addition, because of the large amount of electrical energy required, it is difficult to apply to lower voltage occasions, especially when the voltage of the electric power supply 5 is weakened or weakened, it is more difficult to operate the electromagnet. The function of the $ magnet is disabled. 2 · It is used for higher height phenomena, and then 3 · The size of the electromagnet is limited, no, its instant flushing cleans the space above the hair due to the water pressure field, the electricity caused by the iron core control, when This method has a quick flush effect. It is provided that the flush valve in the center of the board is more closed when the magnetic valve is flushed. The flush valve is opened. The pressure is released. The amount of pressure is not obvious, so it will often occur without being affected. The center of the partition is closed, so when it is in water, it will be affected, which will lead to activities. The water impact force is also high, especially if the drainage channel is blocked if the water pressure is not improved. The top is directly based on the diameter of the drain channel. The opening speed of the valve with a smaller diameter of the drain channel is too slow and not enough. The main impact on the whole is the double valve flusher inside the flusher body and the upper and lower valve seats. , Install an upper and lower valve seat,
